Lexar JumpDrive Sport 1 GB now recognized as 4 MB drive

I have a jump drive that I tried to install some portable software on. When I realized that this took up over 900 MB, I decided to get rid of it and go with something else. After reading the readme that came with it, I deleted the program like it said to do, and reformatted for just in case. Now it is recognized as a 4 MB drive instead of 1 GB. I was finally able to delete the partition in disc management after changing the driver out for another, but it still shows that it only has 4 MB of space instead of 1 GB. My OS is XP service pack 2, and it shows up as only 4 MB on multiple computers. Any suggestions on how to fix this, or am I stuck with buying a new jmp drive?

Ok, the freeware link is kill disk. kill disk didn't work, it was still 4 MB after getting done, the kill disk procedure didn't work either. drive key, well, already tried the HP tool. XP disc management. That hasn't worked, still recognized as 4 MB. finally got spin rite to recognize the flash drive, no joy there either, every scan say it as 4 MB and nothing more. Partition Magic doesn't do the trick. At first it didn't recognize it at all, but after changing the driver out, it saw it and only as 4 MB. And the BG Rescue Linux didn't do it either.

No, I've had a lot more than 4Megs on it before. Had this thing full with a gig. This is something I've done to it. Also, I've used the lexar utility, bootit, that doesn't work either. Is there anything comparable to a bios on jump drives? Or would it be there's a system file that was overwritten that says how many sectors there are?

You might be screwed. I'd try a bootable linux cd like Ubuntu and try to partition/format it with that. Sometimes those things just get screwed up, lots of posts in the past on these boards about people's drives just dying.

Little did i realize that the USB memory stick was branded Micro Center for the U3 Launchpad. I bought it for the flash memory. I did not understand the display sign..... until today. I see the 4MB assigned to the U3 OS, and 0 free space.
